I wonder if perhaps the original unit and the replacement were actually refurbished units just being recycled. The original was a gift, so maybe whoever purchased it bought a refurbished unit to save a little money. Amazon is well known to send refurbished units as replacements, so I certainly won't be surprised if the second unit is a refurbished unit. Back in the day when the PW1 was getting replaced a lot due to screen coloration issues, Amazon seemed to be simply repackaging returned PW1s and shipping them out as refplacements to other customers. Those screens likely were not really refurbished, as in fixed, just repackaged. I think it is very possible that an employee at the return center took a look at the second unit when it was returned and decided it wasn't fixable or worth fixing, and just repackaged it as a refurbished unit. It is likely far less expensive for Amazon to attempt to pawn it off on another customer than to actually replace the screen. Who knows, maybe they have an internal policy of doing just that: First try to pawn it off on another customer. If they are okay with it, then issue resolved. Else if it gets returned again, then actually fix it are part it out.
